IT++

Once in Chalmers I asked my data compression teacher Thomas Erikson if he could suggest some C packets that could perform signal processing algorithms. He said that I could try IT++ , which was developed by him (I'm really proud of being his student) and was free and open source. It was quite attractive to me but I wasn't able to find anything useful due to my little programming experience then. Now I do recommend it to you because it's similar to Matlab but faster and COOLER. Enjoy it!

IT++ is a C++ library of mathematical, signal processing, speech
processing, and communications classes and functions. It is being
developed by researchers in these areas and is widely used by
researchers, both in the communications industry and universities.
Since 2004, IT++ is also being developed as a part of the European
Network of Excellence in Wireless Communications (NEWCOM).
